Benefits of technology

The patent describes a new antenna design that improves performance and simplifies fabrication. The design includes a magnetic substrate that is spaced apart from a coil part using a bonding layer, which enhances antenna performance. The coil part is directly placed on a non-magnetic insulating substrate, reducing the complexity of the fabrication process. The antenna pattern is connected to a connector through a conductive bridge, further simplifying the assembly. The antenna pattern is folded and connected to the connector, as well as formed simultaneously with a wireless charge and communication antenna pattern, improving power transmission efficiency and communication with external devices. Overall, the design allows for improved performance and simplified fabrication of the antenna.

Problems solved by technology

Although the electromagnetic induction technology has been rapidly commercialized while focusing on small-size devices, the power transmission distance thereof is short.
However, a typical antenna assembly embedded in a terminal has a thin thickness and the manufacturing process of the antenna assembly is complicated.

Abstract

Disclosed is an antenna assembly including a substrate, and a wireless charge antenna pattern on the substrate. The wireless charge antenna pattern has a sectional surface including a plurality of inner angles in which two inner angles are different from each other. The antenna assembly includes a wireless communication antenna pattern formed on the substrate and provided at an outside of the wireless charge antenna pattern. The wireless communication antenna pattern has a plurality of inner angles at a sectional surface thereof, and a plurality of angle values of the inner angles provided at the sectional surface of the wireless communication antenna pattern correspond to a plurality of angle values of the inner angles provided at the sectional surface of the wireless charge antenna pattern, respectively.

Description

TECHNICAL FIELD[0001]The disclosure relates to an antenna assembly and a method of manufacturing the same. More particularly, the disclosure relates to an antenna assembly including an antenna, which is wirelessly rechargeable, and a method of manufacturing the same.BACKGROUND ART[0002]A wireless power transmission or a wireless energy transfer refers to a technology of wirelessly transferring electric energy to desired devices. In the 1800's, an electric motor or a transformer employing the principle of electromagnetic induction has been used and thereafter attempts have been performed to transmit electrical energy by irradiating electromagnetic waves, such as radio waves or lasers. Actually, electrical toothbrushes or electrical razors, which are frequently used in daily life, are charged based on the principle of electromagnetic induction. The electromagnetic induction refers to a phenomenon in which a voltage is induced so that a current flows when a magnetic field is varied aro...
